Abstract

To overcome wilting problem in guava by producing wilt resistant plants through grafting procedure using Polypiara seedlings as resistant rootstocks, an experiment was conducted at the Germplasm Centre, Fruit Tree Improvement Project (FTIP), Department of Horticulture, Bangladesh Agricultural University, Mymensingh. The experiment consisted of three varieties (Kazipiara, Swarupkathi and L49), three grafting methods (Cleft, Veneer and Contact) and two types of scion (Hardwood and Softwood).Variety influenced the sprouting and growth of the scion in very few cases but in most cases the effect was insignificant. But the grafting methods and scion type influenced significantly the sprouting and growth of the scion independently and sometimes combindly. Early bud sprouting was noticed in Kazipiara and also in Veneer methods of grafting and Hardwood scion. The highest scion height increase and leaf number were observed in grafting done through Contact method. Hardwood scion contributed better scion growth than Softwood scion.
